摘要： The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The method includes identifying whether a channel forecast value is valid, the channel forecast value being acquired based on applying a learning algorithm to an input comprising channel values estimated based on first reference signals (RSs) received from a base station, transmitting, to the base station, an RS request message for requesting an update of the learning algorithm, based on the determining that the channel forecast value is invalid, receiving, from the base station, second RSs of an RS density determined based on the RS request message, generating an updated learning algorithm based on channel values estimated from the second RSs, and transmitting channel forecast information acquired based on the updated learning algorithm to the base station.

摘要： The disclosure relates to a communication technique of combining a 5G communication system to support a higher data transfer rate than in a 4G system with IoT technology, and a system thereof. The disclosure provides a terminal in a wireless communication system. The terminal includes at least one processor configured to: obtain a codebook set for the terminal; generate uplink signals by using a plurality of codebooks of the codebook set; and control at least one transceiver to transmit the uplink signals to a base station. A first uplink signal of a first resource among the uplink signals is generated based on a codeword of a first codebook among codebooks and a second uplink signal of a second resource adjacent to the first resource among the uplink signals is generated based on a codeword of a second codebook which is different from the first codebook among codebooks.
